|
Service processing
|
Supports the VC-12 services, VC-3 services, VC-4 services, and VC-4-4c concatenation services.
|
|
Overhead processing
|
-
Processes the section overheads of the STM-4 signals.
-
Supports the transparent transmission and termination of the path overheads.
-
Supports the setting and query of the J0, J1, and C2 bytes.
-
Supports one to four channels of ECC communication.
|
|
Alarms and performance events
|
Reports various alarms and performance events, which facilitates the management and maintenance of the equipment.
